A novel and sensitive determination for tetracycline (TC) in crucian carp muscle was developed by using capillary electrophoresis coupled with electrochemiluminescence (ECL) detection. The conditions affected separation and detection were examined in detail. The linearity range of TC concentration was from 0.005 to 10 mu g mL(-1) with a correlation coefficient of 0.9992. The detection limit of TC (S/N = 3) was 1.8 ng mL(-1). The relative standard deviations of the ECL intensity and the migration time for eleven consecutive injections of 1.0 mu g mL(-1) TC were 1.6% and 0.8%, respectively. The recovery of TC was 97.8% (n = 5). After administration of 75 mg kg(-1) TC, the maximum concentration and peak time of TC in crucian carp muscle were 7.33 mg kg(-1) and 8 h, respectively. After administration of TC, TC concentration demonstrated trivial variation in the period from 48 to 96 h. (C) 2012 Elsevier Ltd. All rights reserved.
